Carnivorous plants in Fukuyama City, Japan

[Mujinamo]

I found Utricularia macrorhiza, Utricularia bifida, and Drosera rotundifolia in Fukuyama City, Hiroshima Prefecture, Japan. They were located one station away from the city's main train station. Utricularia macrorhiza was growing very close to the road, in two large artificial ponds for holding water. It tended to grow very close to the shore and I didn't see any in the center of the ponds. I saw like 6-7 different species of dragonflies there as well as a lot of other insects. 

 

 

The second site was a wetland that was near a dam. There's supposed to be Drosera peltata (maybe a different species now), Utricularia uliginosa, Utricularia macrorhiza, Utricularia, bifida, and Drosera rotundifolia there, but I was too late for Drosera peltata and didn't see any Utricularia uliginosa so I wasn't able to confirm its presence there. I also didn't see any Utricularia macrorhiza there or in the water at the dam, but I also didn't look very hard for it since I had already seen it at the previous site. Anyways, I only saw carnivorous plants growing in the left half of the wetland for some reason. The area was quite small, probably around 5 square meters. 

The first plant I saw was bifida, and I actually noticed the stolons first even though there were plenty of flowering specimens. I'm rather embarrassed to admit that it took me around 20 minutes to find Drosera rotundifolia despite there being plenty of them. I think the main thing that threw me off was that there weren't any clumps of plants. They mostly grew as individual plants with the occasional 2 or 3 plants growing together, and weren't the bright red I am used to seeing when looking at wild rotundifolia. After a lot of effort searching, I was able to see a flower stalk and follow it to find a rosette half-hidden by grass. The plants here also weren't very vigorous, having a lot of spindly green leaves. There was some construction going on a little distance away to repair the path and fix part of the dam, but it was downstream so hopefully it doesn't affect the plants. 

I would definitely want to return to this site in the future to look for tuberous Drosera and check for Utricularia uliginosa.
